I think I used poplar for mine.
I like 1x3 because it gives room on the flange to get a drill in with a large chuck. I think there's a book (by Westcott) that gives stability of L-girders. How long an unsupported span do you expect? Mine is generally supported every 30" or less but I have an 8-footer that's clear for 7 1/2 feet.
